Syntax:

-if <expression> [-command1 ... -commandN] [-elif <expression> [-command1 ... -commandN]] ... [-elif <expression> [-command1 ... -commandN]] [-else [-command1 ... -commandN]] -fi

Example 1.

Example illustrating the use of an -if, -elif, -else, -fi construct. Here we compute the -rms of light curves given in the file EXAMPLES/lc_list. Subsequent processing depends on the values returned by -rms. Note the use of nested -if statements.
